Pls don’t include subjective thoughts, or moderators will close this question like they closed our last one (http://stackoverflow.com/questions/7668076/impact-vs-other-javascript-game-engines).
We need game engines that can run on iOS devices and ideally Android devices as well.
Thanks!
Here’s a site which contains a big list of JS game engines:

Also, if you’re interested in this sort of thing, you might want to subscribe to the Javascript Weekly newsletter (or at least read the back-issues from their site). This newsletter is a great way of keeping up-to-date with the latest news in the Javascript world, including news about new JS libraries that come out. Game libraries have features quite often.
Hope that helps.
